Just wanted to put some update here:
- For debricking I soldiered a spi flash which i programmed and flashed with cfe and booted from it, then I flashed openwrt via TTL on the normal memory.
- While I put the latest binary firmware from ASUS RT-AC88U the wifi is still highly unstable and in general can not set channels etc. Something is wrong there.
- I was hoping to put a luks encrypted drive via the usb port but after doing some cryptsetup benchmark the results aren't what i expected (around 30mb/sec, was hoping for 60). It turns out this CPU doesn't have any crypto engine or aes acceleration (at least from what i found)
- In general I'll play a bit more with it, but I might sell it as I'm not getting anything major from this device (well if 160ghz works nicely it will be cool)
